  • Patent number: 9315313
    Abstract: An object of the present invention is to facilitate discharge of the content in a dispensing container having a delamination structure so as to minimize the amount of remaining content. In order to achieve this object, a gas is housed in the internal container 11 to thereby form a gas space S therein and the volume of the gas is 4% or more of the volume of the internal container 11. The gas preferably moves rapidly in the internal container 11 when the dispensing container is tilted to a discharge posture in order to discharge the content M from the discharge port 14. The gas may be encapsulated in a gas bag or the gas may be encapsulated in a gas chamber formed in the internal container 11.

  • Patent number: 9238527
    Abstract: A dispensing container provides that after discharging content, the content which has not been returned to an internal container is prevented from leaking out of a discharge port. The dispensing container has an internal container which contains content and an external container in which the internal container is attached. The external container is provided with a suction port for sucking external air in between the internal container and the external container. A discharge cap is attached to a spout and is provided with a discharge port for discharging the content. The discharge cap includes an inside plug which closes the spout and a cylindrical body covering the inside plug and being provided with the discharge port. The inside plug is provided with a communication port. A valve that is slidable along an axial direction of the communication port is provided to open and close the communication port.

  • Publication number: 20130119092
    Abstract: In order to provide a check valve capable of sufficiently suppressing the mixing of air into the container even if a certain impact is applied to the container and also capable of stably maintaining good pouring of the content, a check valve 10 of the invention is formed of rubber material and manufactured by integral molding. The check valve 10 has a tubular main body 1 having openings 1a and 1b at opposite ends, a lid 3 arranged to close one opening 1a of the main body 1, and a hinge 5 that connects the main body 1 and the lid 3. The lid 3 has a projection 3a on the side surface 3b, the projection 3a coming in contact with a peripheral edge of the opening 1a of the main body 1.

  • Publication number: 20100219186
    Abstract: [Problems] To provide a plastic cap having a pouring cylinder capable of pouring the content liquid smoothly maintaining a constant liquid width even in case the degree of inclination of a container is varied to some extent at the time of pouring the content liquid, and of easily adjusting the liquid quantity. [Means for Solution] A bill 20 is formed at an upper end portion of the pouring cylinder 11 provided in a top panel 5 of a cap body 1, the bill 20 protruding outward in an inclined manner, a lower end of the pouring cylinder 11 is forming a seal surface 17 of nearly a cylindrical shape, a groove 30 is formed in the inner surface of the bill 20 in the pouring cylinder 11 and is extending from an upper end portion of the seal surface 17 up to an upper end of the bill 20, and a seal ring 29 is formed on the inner surface of the upper lid 2 so as to come into close contact with the seal surface 17 which is the inner surface of the pouring cylinder 11 when the upper lid 2 is closed.
